To all whom it may concern:

Be it known that I, CLARENCE H. HAP- ooon, a citizen of the United States, residing at Toledo, county of Lucas, and State of Ohio, am the inventor of certain new and useful Improvements in Scales, of which the following is a specification.

My invention relates more particularly to a scale designed for automatically counting the numbers of a grou or mass of articles each having substantia y the same weight. Thus, in hardware stores, stock rooms of factories and the like where screws or bolts are to be dispensed in different numbers, and in fact 1n all places and situations where it is frequently necessary to count a definite number of small articles from time to time or to determine the numbers of such articles in groups or quantities of the same, my invention will be found of value. But though my invention is in some of its features adapted for use only in connection with counting scales, other of its features are of more general application and not so limited. For the sake of exemplification of my invention, however, I have illustrated and described two preferred forms thereof in the nature of counting scales, it being understood that my invention is not limited to these articular forms but is set forth in the fol owing claims, in which I have endeavored to distinguish it from prior inventions in the art so far as known to me without, however, relinquishing or abandoning any portion of the invention.

Referrin now to the accompanyin drawin i ure 1 is a plan of a preferre form 0 sea e partly insection on the line 1-1 of Figure 2;

Figure 2 is a front elevation partially broken away and with the face plate of the scale removed in order to more clearly show the invention;

Figure 3 is a vertical section upon the line 33 of Figure 2 looking in the direction of the arrows;

Figure 4 is a side elevation of a second form of the invention;

Figure 5 is a plan of the same partly broken away, and with the weight indicator casing removed; and V Fi ure '6 is a section upon the line 66 of Flgure 4'looking in the direction of the arrow.

tor Serial No. 474,788.

The same numeral of reference is applied to 'each part wherever it'occurs throughout the specification. 4

The invention as disclosed in either modification may be generally described as a beam and pendulum scale in which the pendulum is weighted with a specimen or sample of the articles to be counted and the latter placed in the scale pan, the displaceroportional ment of the pendulum being to the number of articles in t e pan and indicated by an indicator and chart.

Turning now to Figures 1 and 3 inclusive, and to the scale shown therein, the frame 4 may be of any suitable character and in the present instance is shown as comprising a chambered casting having le 5 and an upward extension 6, the latter constituting a housing for the chart. The casing is formed at 7 with ears depending from the upper wall thereof and perforated M8 to form bearings 9 for the knife edges 10 of the scale beam 11'. The bearin 9 may take the form of agates seated in t e casing, or the casting may simply be hardened at this point if desired. The beam 11 carries the knife 10 by which it is supported in its bearings and on the shorter end with an extended rod 12 upon 'which a counterweight 13 is adjustablefor the purpose of sealing the scale. At the end of its longer arm 14 the lever is provided with a bearing which receives a stirrup 15 depending from the counterbalancing member in a manner which will be presently described. The counterbalancing member is formed with an arbor 16 which carries a concentric segment 18 and an eccentric segment 19, from the latter of which the stirrup 15, heretofore mentioned, is suspended by a flexible band 20. The concentric segment 18 suspends a counterweight 21 which counterbalances the weight of the stirrup 15. Upon the same casting and rigid therewith is mounted a pointer 23 which travels over The pendulum links are nicely counterbalanced by adjustable weights 75, upon rods 76, 76, extending upwardly therefrom. In order that the effective length of the endulum links 70 may be adjusted, the

inks are each made in two screw-threaded sections connected by turn buckles 77.

The multiplication of the lever mechanism is such that one article placed in the specimen pan 61 will counterbalance a defi nite number of articles (preferably 100) on the platform 33. If, therefore, it is desired to count out one hundred articles, one article is placed in the specimen pan and enough articles are then poured upon the platform 83 to bring the indicator hand 41 to zero position and the pointer 62 into registration with the center graduation on the chart 63. When the indicator hand is in zero position the articles on the platform are exactly counterbalanced by the article in the specimen pan 61. If it is desired to count out five hundred articles, five articles are placed in the specimen pan 61 and enough of the .articles are then placed upon the platform to bring the indicator hand to zero position. The specimen pan 61 may thus be used to count out even hundreds of articles.

From what has been said with reference to the first described form of the invention, it is believed that the operation of the scale when one or more specimens are placed in the pan 73 will be readily understood. The leverage is such and the scale is so arranged that if one of the articles to'be counted is placed upon the pan 73 and a quantity of articles is placed upon the platform 33 the indicator hand will be moved over a number of graduations in the first circle upon the dial to indicate the number of articles in the quantity upon the platform 33., or, if ten articles be laced in the pan 73, the number of articles u on the platform may be read in the second circle, and so on.

If the quantity of articles to be counted is so great as to be beyond the capacity of the chart, enough specimens of the article may be placed in the specimen pan 61 to so nearly counterbalance the load upon the platform 33 that the mechanism may be floated by placing one, ten or one hundred specimens in the pan 73. When one or more specimens are thus placed in the pan 73, the number indicated upon the dial as counterbalanced by the specimens in the pan 73 may be added to the even hundreds counterbalanced by the specimen pan 61, By the use of the non-shiftable specimen pan 61 and the variable leverage specimen pan 73 the capacity of the scale is made very great without impairing its sensitiveness or accuracy in counting small quantities.

While it will be apparent that the illustrated embodiments of my invention herein pendulum comprising a pair of disclosed are well calculated to adequately fulfill the objects primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

Having described my invention, I claim:
